and claimed.

In the accompanying drawings :--Figure' 1 is a vertical section of thegenerator. Fig.1 2 is a section taken on line 2-'2, of Fig. 1. Fig. 3 isa section taken on line 3-3, of Fig. 1 looking in the direction, of thearrow. I Fig. l is an enlarged vertical sectional view through thepiston casing. F ig. 5 is an enla-rged sectional view through the upperend of the piston casing showing the manner of the carbid reeeptacle soas to come in contact with the carbid contained in the upper tank. Itshould 'be understood, however, that the present device is adapted foruse in houses and for other purposes and may be modified as to itsdetallmechanical construction without from the spirit of the invention. vReferring to the drawings will be seen 55 as 1 tee-the use of'the'generator tained in the bottom of the tank. (The providing the gaschamber should be overextends downwardly into the liquid within Withthese and other objects view this I invention consists of certain novelcombina- I' holding the piston rod in a set position.v Fig. -6 is aperspective view of the upper -mean s such as illustrated at 11 forthe'pu-rprevent the splashing of liquid or'water into which comprises atank shape body having a flared bottom 2.

I The base orwater'containmg tank 1 is provided with a substantially invertedcone-shape hopper {l which is open at its lower end as indicated at 5and over this opening '5 is placed a substantially domeshape shield 6,which shield is supported above (the inner face of the hopper a by meansof upwardly extending legs '7' so as to allow the [carbid to readilyslide into the water or liquid conliquid or water is adapted to beplaced in the tank 1 at a sufficient height to extend slightly above thelower end of the 'hopper, r and in view of the fact that the hopper 4'75 the tank l, it will be seen that this willprevent the splashingofthe liquid in case the body of the generator should be su-bjecttosudden jars as would be the case when used 831) course, it should beunderstood that "the water containing tank or base '1 may be prov-idedwith any suitable filling opening." H

A carbid containing section or compartment 8 is detaohaibl y mountedupon the upper end of the base 1 and is provided with a circumferentialflange- '9 upon its lower end :to fit tightly around the upper edge ofthe .basel. A' sealing washer 10 is interposed between the .carbid'containing receptacle 8 and the "base 1 so as to constitute -anair,'gasand water tight joint between the two sections. The carbidcontainingjsection 8 may be provided with-any'suitable pose of allowingthe device to be attached to any desired support such as a vehicle orautomobile frame. The carbid containing section '8 is provided at-itsupper end with an upwardly extending collar 12 upon which is threaded aremovable cap '13 so as to nbrrnally close the -"upper end of the carbidcontaining section 8. "lhis 'cap' may, illOW- ever, be removed when itis so desired.

A pressure gage 5L4 may be earriediby the carbid containing section 8 soas to indicate the amount of gas pressure within the base 1 if i h .1'1ejs A g s pni y pipe. 16 is eonnected to the carbid contain as tocommunicate with the base 1 to allow the passage of acetylene gas fromthe generator.

A carbid delivering hopper 16 is mounted 5 within the carbid containingsection 8 and comprises a substantially inverted coneshape body havingan open lower end 17. A transversely extending guiding bar 18 is carriedby the hopper 16 and this guiding bar 18 is provided with an eye 19through which the vertically extending guiding rod 20 passes. Thisguiding rod 20 carries a helical twisted agitator bar 21 which bar 21terminates in a valve 22 at 15 its lower end. This valve 22 has adepending pin 22, and this pin 22 is pivotally connected to the link 23by means of a pivot pin 24 or may be connected in any desired mannerwithout departing from the spirit 2 of the invention. The carbid isplaced within the upper end of the carbid containing section 8 throughthe opening which is normally closed by means of the cap 13, and thecarbid' is delivered from the hopper 16 2 through the opening 17 whenthe valve 22 is moved away from the opening 17 to the position shown infull lines. One end of the link 23 is pivotally connected to a suportingrod 25 which constitutes a suspending'ineans therefor, and the oppositeend of this link 23 is provided with a longitudinallyextending slot 26which slot receives a transverselv extending pin 27 carried by thevertically extending piston rod 28. The piston rod 28 is in this manners curely held in engagement with the link tions 31 to admit the gas fromthe base 1 into the lower end of the piston cylinder 29. The piston rod28 passes through this cap 30 and is provided with a reduced upper end32 which passes through the piston head 33. This piston head 33 isloosely mounted upon 59 the piston rod 28 and is normally -forced intoengagement with the beveled shoulder 34 of the piston rod by means a ofa tension spring The tension of this spring 35 may be adjusted by meansof a nut 36 which is threaded upon the upper end of the piston rod 28.The piston head 33 may of course be formed of any desired constructionfor the purpose of performing the desired function. The lower end of therod 28 is bifurcated so as to straddle the link 23 similar to the mannerin which the depending pin 22 straddles it as is illustrated in Fig. 8.A coil spring 37 is mountedupon the lower end of the piston rod 28 andis interposed between the cap 30 and an adjusting nut 38., which 2.61--

justing nut 33 is threaded upon the lower end of the piston rod 28 forthe purpose of regulating the tension of the spring 37 The pistoncylinder 29 and section 8 are provided with registering apertures 39which registering apertures will allow the escapement of excess mulatedin the base ii The agitator bar 21 is provided with a toothed periphery40, which will break up the agglomerated lumps of carbid as the agitatorbar passes through the carbid and inthis manner cause only smallparticles of carbid to drop into the base 1, thereby allowing theacetylene gas to be more.

quickly generated than if large particles of ca'rbid were allowed todrop into the base 1.

From the foregoing description it will be seen that when the valve 22 isdrawn away from the opening 17 the carbid with-' in the carbidcontaining section 8 will drop into the base 1 and by mixing with thewater within the lower portion 2 of the base 1 will cause acetylene gasto be generated and as the gas continues to'be generated the piston head33 will 'be forced upwardly thereby drawing the valve 22 to a closedposition over the opening 17. In case the gas should continue to begenerated at an excess pressure the piston head 33 will be "forced stillfarther upwardly against the ten sion of the spring 35 and cause thepiston head 33 to pass beyond the apertures 39 thereby permitting thedischarge of excess gas from i the generator. As soon as suflicient gashas escaped from the generator the piston head will assume itsnormalposition and when sutlicient gas has been used from the base 1,

the piston will again drop in the piston cylinder 29 suflicient to causethe valve 22 to be drawn away from the opening 17.

The piston rod 28 carries at its upper end an eye 41 which eye isadapted to receive the downwardly inclined end 42 of the loclring rod43. This locking rod 13 passes through a guiding sleeve 14; and carriesa knob 45 at its outer end to facilitate the op eration of the lockingpin or rod -13. When it is desired to hold the valve 22 in a closedposition such as for instance when the carbid containing sectionB isbeing filled with the carbid the piston rod 28 is raised to the positionshown in dotted lines in Fig. 1., and the downwardly extending end 42 ofthe pin or bar 43 is forced through the eye 4.1 thereby holding the rod28 in a set position and also holding the valve 22 in firm engagementwith the edge of the aperture 17. Owing to the fact that the inner end12 i of the rod 43 is inclined downwardly it willbe seen that thefarther the pin or rod is is pushed inwardly, the rod 28 will be drawnfarther upwardly.

It, of course, should be understood that gas which has accuwhen it isdesired to fill the carbid receptacle 8, the cap 13 may be removedtherefrom so as to allow the operator to place his hand into the carbidreceptacle 8 and pull upwardly upon the rod 20 and in this manner raisethe plunger 33 to such a position as to allow the locking rod L3 toengage the eye carried by the valve stem 28.

It will be seen that a very simple and eflicient locking means for thepiston rod 28 has been produced, whereby the valve 22 may be firmly heldin a closed position.
